Jasper with javafx does not open by jar

Question

I have a strange problem, I made an application with javafx and jasperstudio and when running inside the eclipse works perfectly. When generating the . jar and run, it works, but if I remonear the directory where the fonts are, it stops working. I had Java pick up where Jasper is, regardless of where it was created. The strange thing is that I have no error, it simply does not generate error. The simple fact of renaming the directory where the sources are the system to. I don’t know where else to run.

    @FXML
public void negAtraso() throws IOException, JRException {

    try {
        BusinessDAODB businessDAODB = new BusinessDAODB();
        arquivo = new File("negAtraso.jasper");
        String caminho = arquivo.getAbsolutePath();
        System.out.println(caminho);
        System.out.println(arquivo.getAbsolutePath());
        List<BusinessPojo> negocios;
        negocios = businessDAODB.negAtraso();


        Report report = new Report(caminho, ownerWindow);
        report.printPreview(null, new JRBeanCollectionDataSource(negocios));
    } catch (Exception e) {
        e.printStackTrace();
    }


}

public class Report {

Try to generate your Jasperreports this way:

URL arquivo = getClass().getResource("/companyname/seupackage/arquivo.jasper");
JasperReports jreport = (JasperReport) JRLoader.loadObject(arquivo);

The Jasper file must be inside your source folder in some package. This way changing the name of the root directory does not affect Jasper.
